My guess is the quiz is old. When I was dx'd the pdoc told me bipolar II was less serious (that was 4 years ago) Recently (about a week ago) I read an article saying that Bipolar II has a higher death rate because those with Bipolar II are less likely to be compliant with treatment since the symptoms are so debilitating. The hypomania in Bipolar II is not as "Destructive" as the mania that comes with Bipolar I, so they're less likely to view it as a problem. The quiz looks only at symptoms. Yes, BP II has less severe symptoms, but overall is more dangerous. Quiz should probably be updated. Good catch laauton!
